Apart from natural death due to age factor or a tragic accident, there are hundreds of other reasons, particularly diseases and conditions that kill millions of people around the world each year. These top causes of death vary from region to region and country to country, depending on the presence of high-risk populations.

Leading cause of death in Nigeria

For example, stroke, diabetes, liver failure, and cervical cancer are some of the top causes of death in Nigeria. Here is the complete list of top causes of death in Nigeria:

Top causes of death in nigeria

Stroke: Approximately 69,785 people die from stroke each year in Nigeria. Strokes occur due to problems with the blood supply to the brain. A stroke is a medical emergency and must be treated as quickly as possible.

Coronary Heart Disease: Coronary heart disease (CHD) is a disease in which plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to our heart muscle. Over time, the plaque can harden that narrows the coronary arteries and reduces the flow of oxygen-rich blood to the heart. If the flow of oxygen-rich blood to your heart muscle is reduced or blocked, a heart attack can occur. Approximately 53,836 people die from this disease each year in Nigeria.

Diabetes: Approximately 31,996 people die from diabetes each year in Nigeria. Diabetes mellitus describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body’s cells do not respond properly to insulin or both.it is one of the leading cause of death in Nigeria.

Prostate Cancer: Approximately 9,629 die from prostate cancer each year in Nigeria. Prostate cancer only affects men. The prostate is an exocrine gland of the male reproductive system, and exists under the bladder, in front of the rectum. This cancer begins to grow in the prostate.

Liver Failure: Approximately 37,329 people die from liver failure each year in Nigeria. It occurs when large parts of the liver become damaged beyond repair and the liver is no longer able to function. Liver transplant surgery is done in major cases.

Breast Cancer: Approximately 13,264 people die from breast cancer each year in Nigeria. Breast cancer starts in the tissue of the breast, mostly in the cells of the ducts or lobules that supply milk to it. These two types of cancer are known as ductal carcinoma and lobular carcinoma.

The breast cancer may remain confined to its origin or spread to other parts of the body through metastasis. When the cancer cells do not affect the surrounding tissues, the cancer is known as in-situ. When cancer left the place of its origin and spreads to other locations, then the cancer is known as metastatic or invasive breast cancer. It is one of the leading causes of death in Nigeria.


Cervical Cancer: Approximately 8,074 people face cervical cancer each year in Nigeria. Cervical cancer is cancer arising from the cervix, the lowermost part of the uterus (womb) in females. More specifically, it is the malignant tumor of the cervix. It starts when there is an abnormal growth of cells in the cervix and these cells have the ability to invade or spread to other parts of the body.

Kidney Disease / Failure: A condition in which the kidneys lose the ability to remove waste and balance fluids. Kidney transplant surgery is majorly performed in this case to save a life. Approximately 16,859 people die from kidney disease each year in the absence of good surgery options in Nigeria.

Lung Disease: Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease.

  1. Airway diseases
  2. Lung tissue diseases
  3. Lung circulation diseases

Lung cancer is a big reason for death. Approximately 11,291 people die from lung disease each year in Nigeria.

Epilepsy: Epilepsy patients should seek safe treatment of their neurological disorders. Approximately 23,311 people die from epilepsy each year in Nigeria.

Liver Cancer: Liver cancer is cancer that starts in the liver. The most common type of liver cancer is hepatoma, and it tends to affect males more than females. Approximately 11,512 people die from liver cancer each year in Nigeria.

Lymphomas: Lymphoma or lymphatic cancer is a rare form of blood cancer that affects the lymph nodes and the lymphatic system that prevents the body against infections. Approximately 3,709 people die from lymphomas each year in Nigeria. Approximately 3709 people die from lymphomas each year in Nigeria.

Parkinson’s disease: Parkinson’s disease is a neurodegenerative brain. A person’s brain slowly stops producing a neurotransmitter called dopamine and a person has less and less ability to regulate their movements, body, and emotions.

Alzheimer’s/Dementia: Alzheimer’s is a type of dementia that causes problems with memory, thinking, and behavior. Approximately 2,357 people die from this problem each year in Nigeria.

Ovarian Cancer: Ovarian cancer refers to cancer that occurs in the ovary. The majority of ovarian cancers arise from the epithelium of the ovary.

Stomach Cancer: Stomach cancer is the accumulation of an abnormal (malignant, cancerous) group of cells that form a mass in a part of the stomach.
